Manual Release Mechanism; Electrical Connection - Cardin Elettronica BL3924 serie Montageanleitung

• Fasten the geared motor (fig. 8) to the base plate using the screws "G" and
self-locking nuts.
• Connect the power, safety device and the second motor/encoder "K" to the
electronics card (fig. 9).
• Insert the operator arm "3" onto the motor drive shaft as indicated in fig. 2
and tighten down using the supplied screw and washer "4".
• Carry on with the assembly according to the type of operator arm:
• 206/BL3924ARM - 206/BL3924SRM (fig. 2)
insert the plastic ferrules "9" into the holes on the curved arm "Det. A-B",
connect the curved arm "5" to the straight arm "3" and to the bracket "6" using
the screws "7" and self-locking nuts "10" after having inserted the zinc-plated
spacer "8" inside the plastic ferrule "9".
• Release the motor (fig. 9, Det "1") by rotating the hexagonal key clockwise
until the motor has been released.
• Fasten the front bracket to the gate using two M8 screws (fig. 4). The posi-
tion of the front bracket is determined by opening the arm to its maximum
extension (with the gate fully closed) and aligning the points 1,2 and 3 (fig. 4).
Next, move point 3 backwards by 100 mm from the point of alignment. The
arm must be in square "M" (fig. 5).
• 206/BL3924DRM To install the straight arm with guide follow detail 1 in figure
2 and the dimensions in figure 5a.
Check the following:
- with the front bracket resting against the gate check that it does not suffer
forcing along the "L" axis (fig. 5) either upwards or downwards * while the
gate is moving. Should this occur either the gate or the geared motor has
been incorrectly installed and this could damage the appliance. Once you
have checked all the alignments fasten down the front bracket to the gate.
* Note: the operator arm 206/BL3924SRM has been fitted with special self-
lubricating bearings at the joints "N"-"O" where it rotates thus allowing the arm
to be inclined leading to a play of ± 8° on the gate (see fig. 5a) while at the same
time maintaining fluent rotation.
• After finishing the installation of the appliance and carrying out the electrical
connection fit the upper and lower covers:
- fit the upper cover "O" and fasten down using the screws "Q" (fig. 10);
- fit the lower access cover "P" and fasten down using the supplied key "R".
• You are advised to fit an electric locking device on the installation (see standard
installation fig. 1).

MANUAL RELEASE MECHANISM

Releasing the gate should only be carried out when the motor has stopped
because of blackouts.
To release the gate use the key supplied with the appliance "R" fig. 10.
Releasing the gate
Slide open the lower access door "P" (fig. 10), slide out the hexagonal key "Det.
2" (fig. 10), insert it into the hole of the release mechanism and rotate it clockwise
until the motor is released. This will release the geared motor and free the gate,
which can then be opened by pushing lightly on the gate.
Locking the gate
Remove the hexagonal key, insert it into the hole of the release mechanism and
rotate it anticlockwise until the motor is blocked. Replace the hexagonal key "S"
in its seat, slide the lower access cover "P" into place and lock it. manually by
pressing on the gate or by reactivating the motor.

ELECTRICAL CONNECTION

Electronic control unit for two dc motor with an incorporated encoder and radio
receiver card, which allows the memorization of 300 / 1000 user codes. The
"rolling code" type decoder uses 433.92 MHz (868 MHz on request) transmitters.
The motor rotation speed is electronically controlled, starting slowly and increasing
in speed; the speed is reduced as it nears the travel limit so as to enable a
controlled smooth stop.
Programming is carried out using one button and allows you to set the system,
the current sensor and the entire gate travel distance.
The intervention of the anticrush/antidrag sensor during the closing and opening
stages causes travel direction inversion.
IMPORTANT REMARKS
Attention! There is no 230 Vac contact on any part of the electronic
card: only low voltage safety current is available. In conformity with the
electrical safety standards it is forbidden to connect binding posts 9
and 10 directly to a circuit that receives power greater than 30 Vac/dc.
(fig. 10)
230 Vac POWER SUPPLY CONNECTION
• Connect the control and security device wires.
• Run the mains power supply to the separate
three-way terminal board that is already
connected to the transformer.
• The master motor "M1" and relative encoder are pre-wired. If you need to
disconnect them (for maintenance interventions etc.) you must replace the
cable following the colour order of the wires as shown in figure 9.
Preparing the motor connection wires
• The kit contains 10 metres of 6-wire cable that should be cut according
to the needs of the installation:
- connect the wires of motor "M2" and encoder "2" to the wiring board of
the slave motor (second motor);
- you must scrupulously respect the motor connection sequence between
the motors and the programmer. The order of the binding post connections
1 to 6 is identical on both;
- run the end of the cable to the terminal board on the master motor and
connect it to the wiring board and tighten down the cable clamp "PC".
Note: If you need to choose a longer cable for particular installations (cut
from the 100 metres of cable supplied in a reel) you must remember that in
order to avoid current dispersion the maximum length of the cable must not
exceed 20 metres.

• Warning! For the correct operation of the programmer the
incorporated batteries must be in good condition: the programmer
will lose the position of the gate in case of blackouts when the
batteries are flat and the alarm indication will appear on the display.
Check the good working order of the batteries every six months
(see page 23 "Battery check").
• After having installed the device, and before powering up the
programmer, release the door (manual release mechanism) and
move it manually, checking that it moves smoothly and has no
unusual points of resistance.
• The controlled load output (binding post 15) is aimed at reducing
battery power consumption (if they are installed) during blackouts;
photocells and other safety devices should be connected to this
output.
• When a command is received, via radio or via wire, the electronic
programmer routes voltage to the CTRL 24 Vdc output. It then
evaluates the state of the safety devices and if they are at rest it
will activate the motor.
• Connecting devices to the controlled output contact also allows
you to carry out the autotest function (enabled using "TEST FI" and
"TEST FS" in the "OPTIONS) and check that the safety devices are
functioning correctly.
• The presence of the electrical current sensor does not dispense
with the obligation to install photoelectric cells and other safety
devices foreseen by the safety standards in force.
• Before connecting the appliance make sure that the voltage and
frequency rated on the data plate conform to those of the mains
supply.
• For the 230 Vac power supply only use a 2 x 1.5 mm
• The cable may only be replaced by qualified technicians.
• An all pole trip switch with at least 3 mm between the contacts
must be installed between the unit and the mains supply.
• Don't use cables with aluminium conductors; don't solder the
ends of cables which are to be inserted into the binding posts; use
cables marked T min 85°C and resistant to atmospheric agents.
• The terminal wires must be positioned in such a way that both
the wire and the insulating sheath are tightly fastened (a plastic
jubilee clip is sufficient).
